Athena query returns values from wrong columns. How to troubleshoot?

I have a simple query in athena, select avg price, group by country. It is returning 4 rows, 1 for canada, 1 for usa, and then 2 rows with dates in the country column. This seems to be a bug. What can be done to understand what is going wrong? I am new to athena completely.

Athena is querying a db in glue that has indexed the metadata of a csv file in s3 with its crawler. I have downloaded the csv from s3, and it looks fine.
